Probe continues into fatal Daintree Ferry car plunge

Police in far north Queensland say they have made a breakthrough in their investigation into yesterday's death on the Daintree River ferry.

A 62-year-old Mossman man drowned when his car went overboard into the river off the ferry around midnight (AEST).

Police say the man's car was the only vehicle on board the south-bound ferry at the time.

Police say the death is not suspicious and a man who was travelling with the driver earlier in the day has now come forward.

Water police, scenes of crime officers and investigators from Workplace Health and Safety and Maritime Safety Queensland are continuing their inquiries today to determine how the car ended up in the river.
